To all whom t may concern.'

Be it known that I, EMANUEL SMITH, a citizen of the United States,residing at Murray, in the county of Shoshone and tate of Idaho, haveinvented certain new and useful Improvements in Pulverizers, of whichthe following is a specification.

Thisy invention relates to mills, and more especially to ore grindersand Crushers; and the object of the same is to provide a pulverizerVwhich will prevent sliming but which may be used wet or dry.

The general idea of the invention is the reciprocation of a heavy memberoverv a flat base mechanically, provided with means for raising one endofthis member slightly off the base at one limit of its stroke so as toadmit a little more of the material being ground or pulverized; and thedetails of the invention consists in the means for carrying out thisbroad idea, one successful method of doing so being set forth in thefollowing specification and shown in the drawings. wherein Figure 1 is aplan view and Fig. 2 a side elevation of this machine complete,

Fig. 3 is an enlarged cross section on the line 3 3 of Fig. 2,

Fig. 4 a still further enlarged sectional detail on the line 4--4 ofFig. 3, and

Fig. 5 a sectional detail on line 5-5 of Fig. 1.

In the drawings the numeral 1 designates a base which may and preferablydoes include a removable wear face 2, and 3-3 are tracks of L-shapedcross section secured by bolts 4 upon the edges of the face 2 andupstanding therefrom. Between these tracks reciprocates what I will callbroadly the rubber 5, motion being imparted to it by a crank oreccentric 6 on a power shaft 7, through a pitman rod 8 or by any othersuitable means, although this will answer. The power shaft should carrya heavy fly wheel 9, and rotary motion may be imparted to this shaft bymeans not necessary to illustrate herein.

The rubber 5 has longitudinal upstanding ribs or flanges 10 along itssides, and preferably two others near its center as indicated at 11, andnear both the front and rear ends, all of these elements having uprightslots 12 in which are movably mounted blocks 13 best seen in Fig. 3.Each pair of blocks has journals forA a short shaft 14 carrying a roller15 at its outer end which may travel on the track 3 and sustain more orless ofthe weight of the rubber, according as the blocks are adjusted intheir slots.

On the tracks are disposedA two wedges 16, Y

ment of the shaft 14, and therefore of the position of the roller 15,will cause the latter to strike the face 17 earlier or later, andtherefore great nicety in such action may be had by means of the twoadjustments.

Any suitable means may be employed for guiding the pair of blocks 13 inthe slots 12 and for adjusting them vertically therein, but as shown Iprefer to provide each block in its lower end with a socket slidablymounted over a pin 22 which rises from the lower end of the slot 12.Also a screw 23 is passed down through the top of the flange 10 into theupper end of the block, where it is held by a pin 24 and after thisscrew is adjusted by turning its head 25, it is held in adjustedposition by a lock nut 26 or by other suitable means. Thus the pin 24which engages a groove 27 around the end of the screw, serves as meansfor swiveling the screw in the block, and the screw 23 at the upper endand pin and socket at the lower end of the block serve as means forguiding and retaining it within its slot 12.

While this pulverizer may be used with success in the grinding of ores,I do not wish to be limited in that respect, nor in the details andproportions and materials of parts, as various changes therein can bemade with* out departing from the spirit of the invention. I do considerit advisable, however, to employ a fly wheel on the driving shaft whichreciprocates the rubber, so that obstructions to its reciprocations inthe wayV of eXtra hard lumps of ore encountered may be overcome by theinertia of the fly wheel without throwing an undueload on the drivingmechanism and without retarding or stopping the reciprocatory motion ofthe rubber.

l/Vhat is claimed is l. ln a pulverizer, the combination with a basehaving tracks along its side edges, a rubber movable bodily on the basebetween said tracks, and means for reciprocating said rubber movablymounted on the base between said tracks, and means for reciprocatingsaid rubber; of shafts adjustably mounted on the rub-ber, each having aroller standing above one of said tracks, and Wedges adjustably mounted-on the tracks With the Wedge faces in the path of said rollers.

8. In a pulverizer, the combination with. a base having tracks along itsside edges, a rubber niovably mounted on the base between said tracks,and means for reciprocating said rubber; of shafts havingV rollersstanding above said tracks, means for mounting said shafts for verticaladjustment in the rubber, Wedges disposed along side said tracks andhaving inclined faces overlying the tracks in the path of said rollers,and means for permitting the longitudinal adjustment of said Wedges.

l. The combination With a base, a rubber movable thereon and having anupstanding flange with an upright slot therein, a shaft passing througlsaid slot, rollers on both ends of the shaft, and Wedges carried by thebase and engaged by the roller when the rubber is reciprocated; of yablock for the shaft mounted in said slot and having sockets in its upperand lower ends, a pinfin the lower end of said slot engaging the lovversocket, a screw through the upper end of the slot, and a swivelconnection between the lower end ofthe screw and the upper socket in theblock. Y In testimony whereof affix my signature in presence oftwowitnesses.
